Change the return type of `getClobbers` function from `const char*` to `std::string_view`. Update the function usages in CodeGen module. The reasoning of these changes is to remove unsafe `const char*` strings and prevent unnecessary allocations for constructing the `std::string` in usages of `getClobbers()` function.
